What GAO Discovered
Numerous technologies for carbon seize, utilization, and storage (CCUS) are all set for wider demonstration or deployment, but several difficulties restrict their use. Carbon capture incorporates technologies that independent and purify carbon dioxide (CO2) from a source, which could be an industrial facility (point-source capture) or the ambiance (direct air capture). Programs of capture technologies at issue resources are experienced in some sectors (e.g., natural fuel processing) but need further demonstration in some of the greatest-emitting sectors (e.g., energy technology). Immediate air seize is not as experienced, but has been carried out at pilot scale. Lengthy time to deployment and higher prices hinder popular deployment of equally sorts of carbon capture in the around expression.
Systems for transporting, storing, and straight utilizing captured CO2 are experienced. Businesses are starting to commercialize utilization systems that transform captured CO2 into beneficial solutions these kinds of as ethanol, sustainable aviation gasoline, and mineral aggregates. However, many CO2-based mostly products are not competitive with standard merchandise, may be excluded from the market by market criteria, and deficiency a standardized strategy for making sure they proficiently cut down CO2 emissions.
Components of carbon capture, utilization, and storage
GAO determined 3 features of CCUS deployment where issues may possibly arise:
- Value. Deploying CCUS is an added expense to doing company but at present delivers few prospects to crank out income. Incentives this kind of as federal tax credits help offset the large expense of CCUS for some but not all emitters.
- Infrastructure improvement. Far more widespread deployment of CCUS would involve a construct-out of infrastructure for each of its factors, which includes transportation and storage. Timing of advancement, negotiating land access, and proximity of services are all troubles impacting this make-out.
- Group engagement. Deploying CCUS projects depends on acceptance by and effective engagement with community communities. In the earlier, unsuccessful group engagement and local opposition have contributed to cancellation or relocation of some CCUS initiatives, though some others have been properly been given.
GAO identified 7 plan choices that could enable deal with these issues or enhance the positive aspects of CCUS technologies. The plan possibilities are probable steps by policymakers, which may perhaps incorporate Congress, federal organizations, state and local governments, tutorial and investigation establishments, and marketplace. In addition, policymakers could pick to retain the status quo, whereby they would not choose more motion beyond current endeavours. See down below for specifics of the coverage solutions and selected opportunities and criteria.
Coverage selections to enable tackle problems or improve added benefits of CCUS systems, with chosen options and concerns
Plan Possibility | Possibilities | Criteria |
Investigation, progress, and demonstration (report p. 20)
Policymakers could enhance assistance for reliable funding of exploration and progress and huge-scale demonstrations simultaneously. |
|
|
Technologies-neutral requirements (report p. 34)
Policymakers could persuade the generation, adoption, or use of technologies-neutral standards. |
|
|
Standardized existence cycle evaluation pointers (report p. 34)
Policymakers could assistance the development and use of standardized existence cycle evaluation guidelines to validate CO2 positive aspects of CO2-dependent products. |
|
|
Framework for land access (report p. 44) Policymakers could help enhancement of authorized or regulatory frameworks to control geologic storage of CO2 at the condition amount. |
|
|
Strategic siting (report p. 44) Policymakers could aid strategic siting of CCUS services. |
|
|
Modify incentives (report p. 55)
Policymakers could modify present incentives to aid obtain for CCUS tasks. |
|
|
Community engagement (report p. 62)
Policymakers could assist and motivate proactive group engagement all over CCUS deployment. |

Why GAO Did This Analyze
In 2021, CO2 arrived at a history significant focus in the Earth’s environment for the contemporary period. Scientific assessments have demonstrated that decreasing CO2 emissions could assist mitigate the negative outcomes of weather alter. CCUS is 1 tool accessible to assist gradual, stop, or most likely reverse the growing amounts of CO2 in the environment.
This report discusses (1) the status of obtainable carbon seize systems (2) alternatives for employing or storing captured CO2 (3) vital challenges that could have an affect on the enhancement, demonstration, and deployment of CCUS systems and (4) possibilities policymakers could contemplate to aid tackle these worries.
In conducting this evaluation, GAO interviewed federal officials, tutorial scientists, industry companies, personal firms, nongovernmental businesses, know-how testing facilities, and federal advisory committees In conducting this assessment, GAO interviewed federal officials, educational researchers, market organizations, personal organizations, nongovernmental corporations, technology testing centers, and federal advisory committees convened an interdisciplinary meeting of 27 authorities with assistance from the Countrywide Academies of Sciences, Engineering, and Drugs and reviewed suitable literature. GAO is pinpointing policy possibilities in this report.
